Problems solved by technology

[0004] The whole process takes a lot of time, and it is difficult to ensure that when the audio equipment plug is pulled out from the adapter, the MIC pin will be powered off immediately
Therefore, it is possible that the GND pin of the audio device will touch the shrapnel connected to the MIC pin, but the MIC pin has not been powered off, and then there will be current flowing into the GND pin of the audio device, causing the audio device to output POP sound, reducing user to experience

Abstract

The present disclosure relates to a Type-C adapter including a Type-C interface connected to the Type-C interface of a terminal, wherein when the Type-C interface is connected to the Type-C interface,the idle pin of the Type-C interface is connected to a first component and the first component is connected to a first level; an audio interface connected to the plug of an audio device; a first spring disposed in the audio interface and connected to the idle pin; and a second spring disposed in the audio interface and connected to the second component of the audio interface, wherein the second component is connected to a second level. When the audio interface is disconnected from the plug of the audio device, the first spring and the second spring are disconnected. According to the embodiment of the present disclosure, the MIC pin can be powered off in a shorter time while the plug of the audio device is pulled out of the audio interface, so as to ensure that the MIC pin has been poweredoff when the GND pin of the plug of the audio device comes to contact with the MIC pin, thereby preventing the current in the MIC pin from flowing into the plug of the audio device and causing POP tones.

Description

Technical field [0001] The present disclosure relates to the technical field of terminals, and in particular to a Type-C adapter, terminal and electronic equipment. Background technique [0002] In order to reduce the space occupied by the Audio jack headphone interface in the terminal, more and more terminals have cancelled the Audio jack headphone interface. For example, in a terminal with a Type-C interface, an adapter can be connected to the Type-C interface, and an audio device plug can be further connected to the adapter. [0003] But when the audio device plug is pulled out from the adapter, the GND pin of the audio device will contact the shrapnel connected to the MIC pin in the Audio jack interface of the adapter. The current way to control the power off of the MIC pin is that the power management chip of the terminal detects whether the CC pin of the Type-C interface of the terminal is powered off, and then transmits the control signal to the power supply control module ...
